With this arrangement there is no neutral conductor available. For this reason, the following
optional accessories can be used for establishing this network:
● 2 x autotransformer 3KC9824-1. For information, see the section titled Installing and
connecting an autotransformer (400 V / 230 V) (Page 79).
● For the power supply: Power supply kit 3KC9830-, 3KC9831-. For information, see the
section titled Connecting power supply kit 3KC9830-, 3KC9831- (4-pole) (Page 92).
Note
The F1 fuses must be installed as closely as possible to the tap.
The F2 fuses must be fitted as closely as possible to the output of the autotransformer.
The dual power supply (DPS) accessory is not required with the 3KC8 transfer switching
equipment since it is supplied with power via two inputs of the electronic module.
